Humax TV fault
Have a Humax LU23-TD2 - a 24" LCD with analogue and DTTV tuners. The DTTV
side has failed - just a blank screen. No reaction when you try changing channels - and if you do a scan, it runs through the analogue side, then stops when it swaps to the digital tuner. It's in the kitchen, and not a total disaster as I have a feed to it from my PVR in another room - so can still use it, but it would be nice to sort it. I'm not familiar with modern TVs - any chance it uses a separate part of the power supply to feed this tuner, and that has failed? I'm rather gutted - it was expensive for a set that size, only about 5 years old, and not heavily used. About a couple of hours a day if that. -- *You sound reasonable......time to up my medication Dave Plowman London SW To e-mail, change noise into sound. |

Good chance you'll find one. NT |

Quick Google suggests you are not the only one... AFAICT it's a single 5v supply. Might not be the tuner of course, it's only supplying differential baseband IF, the problem could be in the next chip along... It looks like its using a td1318af/ihp-3 tuner (pic of main board here http://flattvparts.co.uk/index.php?m...oducts_id=5015) Lee |
